Flash was proprietary, didn't have a specification and only one real implementation ever existed.

  Flash was using actionscript which was ecma262-3/4.

    ActionScript only "existed" on the authoring side. Scripts were compiled to (proprietary) bytecode before being embedded in the SWF file. Besides, there's a lot more to SWF than the scripts.

  What is all this BS about it being proprietary... https://www.adobe.com/content/dam/acom/en/devnet/pdf/swf-file-format-spec.pdf https://www.adobe.com/content/dam/acom/en/devnet/pdf/swf-fil... Straight from the horse's mouth, as they say. There's also a few other implementations, although they found use embedded in games and such instead of being browser plugins.
